TANK.

To all whom it may concern:

Be it known that I, DANIEL FRANCIS lVrnTMoRn, a citizen of the UnitedStates of America, and a resident of Trenton, county of Mercer, andState of New Jersey, have invented certain new and useful Improvementsin Tanks, of which the following is a specification.

The object of my invention is to improve the construction of tanks,especially wooden tanks designed for flushing purposes,to lessen thenumber of parts and to simplify the making and putting together of thetank and thereby to provide an improved, durable, strong and water-tighttank.

In the construction of tanks which are made of several piecesdove-tailed or otherwise secured together it is important that as fewoints as possible should exist, inasmuch as moisture is apt in time toforce its way through said joints and also because after a time thejoints are apt to part or work loose, and it is also important ifpossible to have the sides and front of the tank made of a continuousunbroken piece of wood or such other material as may be used in theconstruction of the tank. Wood is the most usual material employed inthe manufacture of such tanks and it is important that the sides andfront should be of considerable thickness to secure the necessarystrength. The rounded front corners must also be of good thickness anddifficulty has heretofore arisen in securing this desired thicknesswithout multiplying the number of parts and joints and thereby impartingan undesirable weakness into the structure. To remedy these defects andto accomplish these objects I make my improved tank with substantiallystrong and thick side-pieces, front, and back pieces, and secure thefront and side-pieces at the meeting corners by a single key at eachcorner, while at the same time I reinforce the sides and front and makea permanent water-tight body by covering the front and side-pieces witha single continuous piece of veneer, which extends entirely over theirouter surfaces and thereby forms a solid water-tight surface at thecorners as well as at the sides and front.

In the accompanying drawings I have shown one form of tank embodying myinvention, in which:

attached to the veneer strip and spread out fiat. Fig. 2, is a top viewof the same. Fig. 3, is a top view of the tank body assembled together.Fig. 4:, shows the relative size and shape of the key, as to length,breadth, and thickness.

Same letters indicate similar parts in the different figures.

A is the front piece.

B, C, are the side-pieces.

D, is the rear or back-piece.

E, is the continuous veneer covering for the sides and front of the tankincluding the rounded corners.

F is the key by which the edges of the front-piece and the front edgesof the side pieces are fastened together. As shown, these meeting edgesare provided with the grooves a, b, in which the key fits snugly andthus makes a water-tight joint at the corner. A facing of crinoline orother suitable substance is preferably cemented or otherwise attached tothe inner side of the veneer be tween it and the wooden front and sidepieces of the tank so as to make a more perfect water-tight structure.

The method of forming and associating the tank is as follows :The piecesA, B, C, and D, are first formed out of suitable material, as wood, ofdesired strength and thickness, the forward edges of the sidepieces Band G being formed with the grooves Z), 7),-and the edges of the frontpiece A being formed with the grooves a, a. The veneer F is alsoprepared of a size suitable to form the entire front and sides of thetank and to this is glued, cemented or otherwise attached a layer ofcrinoline or other water-proof material. The veneer is spread out flatand by suitable glue or cement the front A, and side-pieces B, C, areattached thereto, leaving sufficient space between them as shown in Fig.2, to allow for the bend at the corners. The keys F, F, previouslyformed are inserted in the grooves 6, Z), as shown in Fig. 2. The partsare now ready for bending into shape. This is done by carefully bringingthe side-pieces around into a position at right angles to the frontpiece,the key entering the grooves, a, a, as the corners close untilfinally the body of the tank is formed as shown in Fig. 3. The back D isnow set in place. It is obvious that in most cases it will be necessaryto render the veneer temporarily pliable by steaming before the bendingbegins. The bottom of the tank is then inserted in the usual Way and thetank becomes complete and ready to be finished according to taste.

The great simplicity of construction, the few parts involved, and thequickness with which the structure can be made and put together are, Ithink, obvious Without further explanation. And it will also be seenthat a tank thus made will have the strength and finish, without thedisadvantages of more elaborately built tanks.

1 claim:

1. An article of manufacture comprising a plurality of members, a.relatively thin layer of Wood securely held to said members, saidmembers being cut at an angle with relation to their outer surface andforming abutting ends for the opposed members and each provided vvith acurved outer surface at the ends forming a seat for the layer of wood, agroove in the end of one of the members and a tongue formed on the endof the other member, the tongue adapted to be received in the groove forlocking the members together.

A receptacle of the character described, comprising a plurality ofmembers, a rela tively thin layer of Wood securely held to said members,said members being cut at an angle With relation to their outer surfaceand forming abutting ends for the opposed members and each provided witha curved outer surface at the ends forming a seat for the layer of Wood,a groove in the end of one of the mei'nbers and a tongue formed on theend of the other member, the tongue adapted to be received in the groovefor locking the members together, to form the sides and front of thereceptacle, and a base member and back member adapted to be secured tosaid side and front member to form the completed receptacle,substantially as described.
